Abstract
An electrical submersible pump assembly (ESP) includes a pump section, a motor section, and a seal section. In one embodiment, an exterior of the pump section defines a gripping indentation above the pump intake. Alternatively, a clamp member may be provided that surrounds the pump, wherein the clamp member defines the gripping indentation. A collet adapter is affixed to an upper end of a shroud. The collet adapter has gripping members that engage the gripping indentation for attaching the shroud to the electrical submersible pump assembly. The collet adapter is provided to ease installation of the motor shroud onto the ESP as well as to ease removal of the motor shroud from the ESP. The collet adapter of the present invention eliminates precise alignment and bolt-on requirements of typical motor shroud mounting techniques.
